In a small bowl, whisk together egg, cottage cheese, and vanilla extract.
In a larger bowl, combine all-purpose flour, protein powder, baking powder, and light brown sugar.
Then, cube the butter and add it to the dry ingredients. Start working it with your fingers to make sure as much of the butter is covered with the flour mixture as possible.
Then, pour in the wet ingredients and combine the dough with your fingers. Roll it into a ball, it will be quite sticky.
Cover the counter with flour and place the dough on it. Roll with a floured rolling pin until the rectangle is 10’’ x 8’’. The dough might be quite sticky, just add a bit more of flour.
Add the butter to the small bowl and microwave for a few seconds until it melts. Mix it with brown sugar and cinnamon.
Cover the dough with the cinnamon filling, and spread it around as much as possible. Then, take the dough by the corners and roll it up into a tight cylinder.
Wrap the dough tightly with plastic wrap and place it in the freezer for 1 hour or in the fridge overnight.
Preheat the oven to 400F and place parchment paper on a baking sheet.
Take the dough out of the freezer or fridge, cut off the edges and cut it into 4 equal rectangles. Then cut each rectangle diagonally to form scones.
Place them on the baking sheet spacing them apart, brush them with milk and bake in the oven for 16-18 minutes.
Serve them warm.
